High Cur

Evert Bakker (PA2KW)
Hello,

 

I do have a K2 and KPA 100 (build-in).

For some reason I do get HiCurr messages on a few band (which I didn't get
before)

I did a test with a dummy (50 Ohm up to 1 Ghz) and a Bird 43 power meter

 

The result is:

 

28.500   12,3V / 2,66A   100W+

24.900   12,3V / 2,44A   100W+

21.150   12,2V / 2,46A   100W+

 

18.100   12,1V / 3,72A   100W+

14.150   12,2V / 3,80A     90W

10.120   12,2V / 3,80A     80W

 

  7.070   12,4V / 2,26A   100W+

  3.550   12,4V / 1,92A   100W+

  1.825   11,9V / 2,10A     90W

 

HiCurr parameter was set to 3,80A

 

Especially 18, 14 and 10 Mc bothers me as there are the currents excessive
in relation to the other bands..

What could be wrong?

 

Thanks in advance,

 

73's, Evert PA2KW

Evert,

Take a look at KPA100 resistors R19 and R20.  If they have blue-gray
bodies, they are likely to be inductive (which causes the problem you
mentioned).

The new non-inductive resistors have reddish-brown bodies andcan be
obtained by a note to [hidden email].

Now off to more FDIM/Dayton fun.
